标识符

Groovy 标识符以字母、美元符号或下划线开头，不能以数字开头。下面是合法的标识符：

def name
def item3
def with_underscore
def $dollarStart

下面是非法的标识符：

def 3iter
def a+b
def a#b

println("hellof grovvy");
println("hellof grovvy2")
println "hellof grovvy3"

输出:

> println("hellof grovvy");
> println("hellof grovvy2")
> println "hellof grovvy3"
hellof grovvy
hellof grovvy2
hellof grovvy3
